That isn't really a power regulator IC despite what the schematic says. That is a precision voltage reference feedback IC that feeds the opto coupler.

The first thing to check is capacitor C609 in the primary circuit. Also, get a magnifying glass and bright light and look for any circular solder cracks on the transformer pins.
